Assume we have a data frame in Python Pandas that looks like this:
df = pd.DataFrame({'vals': [1, 2, 3, 4], 'ids': [u'aball', u'bball', u'cnut', u'fball']})
Or, in table form:
ids vals
aball 1
bball 2
cnut 3
fball 4
How do I filter rows which contain the key word “ball?” For example, the output should be:
ids vals
aball 1
bball 2
fball 4
